It may be that the wrong boot device [USB, Optical Drive, etc] is chosen.
Choose F9 from the startup menu then chose your hard drive as the boot device.
This is a 'one time' boot device option.
If this works then you will need to reset your BIOS defaults so that your hard drive is automatically selected as the first boot device.
- Chose F10 key from the startup menu to enter the BIOS settings menu.
- Press the F9 key to reset the BIOS to the default settings [which will reset your hard drive as the first boot device].
- Press the F10 key to save the changes and exit the BIOS settings menu.

OK, just go with the second option then. Probably easier.
Use F10 to enter BIOS Setup then F9 key to 'Restore Default settings', which will set your hard drive as the first boot device, then F10 key to save your changes and reboot.
If this doesn't work then it is likely that your Operating System [Windows] has become corrupted and needs to be recovered or re-installed.
You can try this method first:
